In Bangladesh, free-range duck farms provide opportunities for the generation of novel influenza A viruses as evidenced by the emergence of an unusual A(H1N7) virus in 2023. Continued surveillance of such environments for the potential emergence of influenza A viruses with novel properties remains a priority.

Mucoepidermoid carcinoma (MEC) is a salivary gland tumor commonly arising from the parotid gland. MEC has various presenting symptoms, including a painless, slow-growing mass below or anterior to the ear lobule. However, an unusual presentation can also be in the form of post-auricular swelling. Other more common benign differentials for post-auricular swelling include lymphadenopathy, epidermoid cysts, and lipomas. Thus, diagnosing a postauricular swelling as MEC solely based on clinical presentation is challenging, and a high suspicion, as well as a multidisciplinary approach with various radiological investigations such as computed tomography (CT) and magnetic resonance imaging (MRI), are required in collaboration with histopathological assessment for an accurate diagnosis of this malignancy. Prognosis depends on various factors, including the grade of the tumor, the patient\'s age, and comorbidities, as well as the stage at the time of diagnosis. Early diagnosis and surgical intervention are the mainstays of treatment, which can be followed by adjuvant radiotherapy based on the stage of the malignancy. This is a report of a patient who presented with post-auricular swelling, which was initially misdiagnosed as a benign necrotic lymph node. After further evaluation, it was found to be a mucoepidermoid carcinoma of the parotid gland, which was managed by surgical excision and radiotherapy.

UNASSIGNED: Cystic hygromas are congenital lymphangiomas that arise from a developmental anomaly in the lymphatic system. Typically detected in early childhood, their incidence in adolescents and at the chest wall or axillary area is rare.
METHODS: We report two cases, a 14-year-old male child (Case I) and a 1-year-old male infant (Case II), who presented with swelling in unusual locations, the right axillary region and the right anterolateral chest wall respectively. Local examination findings were indicative of a cystic hygroma in the first case, while in the second case, characteristic transillumination was not seen due to a complication: hemorrhage within the cyst. The diagnoses were established after a correlation of the patient\'s history, and clinical findings with radiological investigations. Both underwent surgical intervention and had no complications. Histopathology of the post-operative specimens confirmed the diagnoses.
CONCLUSIONS: The diagnosis of cystic hygroma is made in the totality of thorough history taking, clinical examination, and radiological and histopathological investigations. Though most cases typically manifest before the age of two years and in the cervicofacial area, unusual locations and delayed presentation can occur. Surgical excision is a safe and effective treatment modality for these lesions.
CONCLUSIONS: Although a rare entity, cystic hygroma should be considered a possible differential diagnosis of any swelling in the pediatric population.

UNASSIGNED: An unusual nasopharyngeal foreign body in a very young child with no clinical symptoms is a rare case presentation.
UNASSIGNED: A nine-month-old child presented with a suspected history of foreign body ingestion without any clue to the parents about the nature of the foreign body. X-ray of the nasopharynx revealed a sharp unusual metallic \"Louis Vuitton\" shoe logo that the child had accidentally inserted into the nasopharynx via the oral cavity while playing. Foreign body was removed under general anesthesia without complications.
UNASSIGNED: X-ray nasopharynx should be included in the examination of a suspected case of foreign body ingestion, as an unusual shape of foreign body can even produce no clinical symptoms but still pose a potential life threat due to its dislodgement into the airway if missed or delayed.

The coeliac trunk, the first anterior branch, often originates at the level of the T12 vertebral body, right below the aortic hiatus, as the first ventral branch of the abdominal aorta. It commonly divides into the left gastric, common hepatic, and splenic arteries. We report a rare variation in the branching pattern and course of branches of the coeliac trunk in two donated female cadavers during routine abdominal dissection. It is essential to understand the coeliac trunk and the distinctions in its origin and branching pattern to perform efficient upper abdominal surgical and radiological procedures and to adopt novel interventional and treatment options for hepatic cancers. As anatomists, we are also attempting to link our study\'s variations to their embryological genesis.
İlk ön dal olan çölyak trunkus, abdominal aortanın ilk ventral dalı olarak genellikle T12 vertebral cisim seviyesinde, aortik hiatusun hemen altından çıkar. Genellikle sol gastrik, ortak hepatik ve splenik arterlere ayrılır. Bu yazıda, bağışlanan iki kadın kadavrada, rutin abdominal diseksiyon sırasında çölyak trunkusun dallanma paterninde ve seyrinde görülen nadir bir varyasyon sunulmaktadır. Etkin üst abdominal cerrahi ve radyolojik prosedürler gerçekleştirmek ve karaciğer kanserleri için yeni girişimsel ve tedavi seçeneklerini benimsemek için çölyak trunkusu ve kökenindeki ve dallanma paternindeki farklılıkları anlamak çok önemlidir. Anatomi uzmanları olarak biz de çalışmamızdaki varyasyonları embriyolojik oluşumlarıyla ilişkilendirmeye çalışmaktayız.

Chronic mesenteric ischemia (CMI) is a rare cause of abdominal pain with risk factors as Diabetes, Hypertension, smoking and age above 65-year-old age. A 55 -year-old man, a heavy smoker, with no other risk factor for chronic mesenteric ischemia, presented with a recurrent episodes of abdominal pain. Many differential diagnoses were excluded, CT angiography was showed Inferior Mesenteric artery (IMA) and superior Mesenteric artery (SMA) stenosis, then the Intervention was done successful. Gastric ulcers that are resistant to treatment, H. pylori negative and with no history of non-steroidal anti-inflammatory drugs (NSAID) use should be investigated for a possible ischemic.

Aim of our study was to report unusual presentation of mucormycosis in patients, who were recovered from COVID-19 infection. This was a prospective observational study, undertaken at Ravindra Nath Tagore Medical College, Udaipur, India, over a period of last 3 months (April-June 2021). All patients with maxillofacial and dental mucormycosis were included in the study. All patients either have COVID-19 infection or recovered from it. Eight (40%) patients had history of use of corticosteroids for COVID1-19 infection, fifteen patients had either known case of diabetes or newly diagnosed diabetes with uncontrolled blood sugar at the time of presentation, three (15%) patients were in pre-diabetic state with HbA1c between 6.0 and 6.5% and two patients had no diabetes. None of patients had diabetic ketoacidosis and only one patient reported complete loss of vision with dental symptoms. There was unusual presentation of mucormycosis in form of loosening of teeth in uncontrolled diabetes. Injudicious use of steroids and uncontrolled diabetes are two main risk factors, so eyes should be kept on both of these.

Hydatid cyst is an anthropozoonotic disease caused by Echinococcus for which man is an accidental intermediate host. The hydatid disease commonly involves the liver and lungs. Involvement of extrahepaticopulmonary sites is extremely rare and only a few isolated cases have been reported. In 2022, a 49 year old female from the southern part of Indian subcontinent presented to us with recurrent hydatid cyst of liver co-existing with hydatid cyst of the left broad ligament, twenty years following the initial procedure. She underwent exploratorylaparotomy and cystectomy and was then managed by ERCP and stenting following which she is asymptomatic till date. Though there are no hard and fast rules, the management of such cases mandate proper exploration to avoid any recurrence. Tailored surgical approaches maybe required according to the patient condition for effective, safe and recurrence free treatment of hepatic hydatidosis.
